The Hidden Invasion: How New Jersey’s Bustling Port Authority Is Becoming a Gateway for Exotic Rodent Species
As cargo containers from around the world arrive daily at the Port of New York and New Jersey, they’re bringing more than just goods—they’re inadvertently introducing exotic rodent species that threaten local ecosystems and create new challenges for homeowners and businesses across the region.
The Growing Threat at Our Doorstep
The Port of New York is New Jersey is the U.S. East Coast’s largest port, moving over 7 million TEUs (over 4 million containers) of cargo to a large local and inland consumer base. PANYNJ Port Director Bethann Rooney says the port expects to see annual volumes rise to 17 million TEU by 2050, almost double its throughput in 2021. This massive increase in shipping activity directly correlates with increased opportunities for invasive species introduction.
Countries are concerned about invasive species traveling the world on shipping containers. International shipping industry fears new legislation on the issue. Molnar et al. 2008 documented the pathways of hundreds of marine invasive species and found that shipping was the dominant mechanism for the transfer of invasive species. This research underscores the significant role that ports like New Jersey’s play in the global spread of unwanted species.
How Exotic Rodents Hitch a Ride
A cargo ship can stretch a fifth of a mile and carry more than 10,000 containers, each holding thousands of items that have already moved by train or truck across great distances. At any point during these journeys, native species can latch onto items or their packaging and wind up on the deck of a ship headed for another continent.
Also known as “ship rats,” roof rats are typically found in tropical areas but have often been unknowingly transported to New Jersey on ships. These rodents, along with other exotic species, find ideal conditions in shipping containers and port facilities. Ants, cockroaches, beetles, and rodents commonly infest containers.
Thanks to its international seaport in the city of Cotonou, the Republic of Benin is at the heart of intercontinental trade between West African coastal as well as hinterland countries and the rest of the world. As a consequence, the APC constitutes a particularly favourable site for exotic rodents introduction and subsequent spread towards landlocked countries. This same pattern occurs at New Jersey’s ports, where exotic rodents can establish populations and spread throughout the region.
The Expanding Problem
Growing numbers of containers entering Atlantic and Gulf Coast ports raises the risk of additional introductions. Insects associated with imports from semi-tropical ports in Vietnam entering the U.S. through Gulf or southern Atlantic ports might well find these regions hospitable. Of course, containers are then sent on from the ports to distribution centers – presenting opportunities for pest introductions in inland areas. New or expanded distribution centers include Atlanta and Appalachian Regional Port and Statesboro Airport in Georgia, Rocky Mount, North Carolina; Huntsville, Alabama; Portsmouth and Front Royal, Virginia.
The most common types of rats in New Jersey are brown rats and black rats—both types introduced species to the region. These established populations create competition for resources and can carry diseases that threaten both native wildlife and human health.
Health and Environmental Risks
Rats are very well known for inhabiting cities and rural areas alike, such as all over the state of New Jersey, often bringing disease along with them, such as rabies and Seoul virus, which is a type of hantavirus. Rat pest control in New Jersey is important because these pests can spread over 35 different diseases through direct contact, droppings, and food contamination.
Invasive species are serious trouble, causing an estimated $120 billion in damage each year, according to the U.S. Department of Agriculture. The economic impact extends beyond immediate health costs to include damage to infrastructure, agriculture, and natural ecosystems.
The Challenge of Detection and Control
Keeping alien insects, animals, plants, seeds and pathogens from entering through the country’s 300-plus ports is the job of U.S. Customs and Border Protection (CBP). Every day, more than 2,300 specialists inspect shipping containers, bulk produce, wood packing material and passenger baggage delivered by airplanes, ships, trains, trucks and international mail. Last year, CBP officers conducted 22,638,509 passenger inspections and 705,510 cargo inspections. Despite these efforts, many exotic species still slip through.
Her officers once vacuumed 34 pounds of seeds adhered to the outside of a shipping container. Khapra beetles are found in dirt on the floor of containers because shippers don’t bother to sweep them out in their home country. This demonstrates how easily rodents and other pests can hide in cargo shipments.

Taking Action
The introduction of exotic rodent species through New Jersey’s ports represents a growing challenge that requires both regulatory oversight and individual action. The global movement of containers and cargo can unintentionally introduce and spread invasive pests, posing serious risks to agriculture, forestry and natural resources. Container flows are complex, crossing multiple borders, involving different modes of transport and passing through many hands. From manufacturers and exporters to freight forwarders, logistics providers, warehouse operators, carriers, importers and regulators, everyone in the supply chain has a role to play in preventing the spread of pests.
For New Jersey residents, staying vigilant about rodent activity and working with qualified pest control professionals is crucial. Early detection and professional intervention can prevent small infestations from becoming major problems, protecting both individual properties and the broader community from the impacts of these unwanted invaders.
As international shipping continues to grow and climate change creates more favorable conditions for exotic species, the partnership between port authorities, regulatory agencies, and local pest control professionals becomes increasingly important in safeguarding New Jersey’s homes, businesses, and natural environments from this hidden invasion.
